Dale: Call the Piano Exchange in San Diego (619) 298-5313 and ask about the Gulbransen products. The owner of the Piano Exchange also owns Gulbransen, and they have several products especially designed to install in pianos. Some have accompaniment features, so you can play and have background sounds which follow your melody. It is based on a strip of switches which install under the keys, and a control unit. I'm not up on all the latest developments, so you can ask when you call. Paul McCloud, RPT San Diego, CA
